For the one-hour drive to my brother and sister-in-law’s home, I told them about my talks with Mom and Dad, and talked to Doug and Sheri about our ideas about the wedding service and how they might fit into it. I didn’t want either of them to be caught off-guard by something my mother or father said to them. I also gave them the option of participating ‘conservatively’ in the wedding and staying over with my parents, but they both laughed and explained that they were so looking to the wedding and what promised to be the orgy of the century afterwards or during or however we wanted it.

Doug accepted my invitation to be my best man. I had been the best man at his wedding years earlier despite my young age at the time. Doug was almost six years older than me, and he and Sheri had been married about twenty years. They had a nineteen-year-old daughter and an eighteen-year-old son; a gorgeous young niece and handsome nephew.

I asked, “What about your kids? Would they want to participate in our wedding?”

Doug shook his head. “I’m not sure I want to expose them to what’s going to happen down on the island.”

Sheri intervened and overrode my brother’s remark, “Yes, they’d love to come and be full participants. They already have experienced lots of sex, some in what I’ll call group and unusual situations.”

Doug exclaimed loudly, “WHAT? What do you mean? What have they been doing?” He looked totally stunned.

Sheri shook her head. “Honey, they are tuned in to the whole scene as well as their sexuality. They just don’t talk to you about it, partly because you want to continue to think of them as virgins until they’re thirty-five.”

Doug said, “What about the group situation you just talked about?”

“Lori has had her steady boyfriend for what, three years now? And there are two other male friends whose names I forget just now. They’ve all gotten together and made love to Lori to her great orgasmic delight. She loves group sex. Ace has a similar situation with his girlfriend, except she’s often involving her BFF in their lovemaking, sometimes even with his best friend.”

Doug said, “Excuse me for being so out of touch.” There was a tension in his voice that hadn’t been there earlier.

Sheri leaned over and kissed her husband on the cheek. “Honey, I love you. I’ll try to let you get a little more involved in their sexual lives. Just don’t berate them on any of this or I’ll cut you off for a year.” At least she was laughing.

He laughed. “No, not my plan.” The initial discovery had upset him, but he seemed to be coming around rapidly.

Doug looked over into the backseat at me and said, “So, I guess the answer to your original question is ‘Yes,’ involve Lori and Arthur in the service. They’re hardly the cute little ring bearer or flower girl they would have been fifteen years ago, but I’m sure you’ll think of a role for them.”

I said, “And to be blunt, what should we do if they want to participate in the sex that’s sure to be going on the rest of the week – and I include myself and Fran in that question, just in case.”

Doug said, “Oh, God, I don’t want to know. Just remember you’re their uncle.”

Sheri laughed and added, “If either of you get your hands on them, I hope you teach them some of that Tantric sex stuff you are so good at. You have my blessing to fuck their little brains out of their heads, too.” She laughed all that much harder at her last statement.

Back at Doug and Sheri’s home, we quickly unpacked, showered, and swapped partners and started to make out in the living room. I was told that Lori and Ace (Arthur) were both out for overnights with friends. Sheri speculated they were probably on their fourth round of sex by that time, so we had to take some serious steps to catch up.

I proceeded to eat Sheri to three orgasms in a ten-minute period as she tried to push my head up inside her cunt. My head wouldn’t fit, but my fist did, and soon I was doing things to her that she thought might be illegal in most states because they felt too good. After about four G-spot orgasms, I found Sheri’s A-spot with my fingertips and together with my tongue on her clit, brought her to a peak slightly higher than Mount Everest. I worried that her screams might bring the police.

I felt sure that Doug had never given Sheri that kind of experience. I’d been somewhat competitive with him growing up despite our age difference. I found some mile satisfaction in my accomplishment.

I avoided the whole Big Steve Experience where Sheri would pass out. At least to start, I wanted a cogent love partner and not one I’d worn out before we got to the main agenda items for the night.

Next to us, Fran was beautifully naked and working especially hard to make Doug reach a state just shy of his own mountain peak. She’d work him up with lips, tongue, breast play, tit-fucking, and then her pussy, and then back him down. Doug’s cock gradually turned a royal purple color suggesting that most of the blood in his body had packed into his thick shaft.

Fran then got him fucking her in the missionary position on the sofa. Doug went wild, moving faster than I’d ever seen him in my life. His whole body was a blur as it oscillated above her, pumping into my fiancée.

Finally, Fran had Doug cum deep inside her. I figured that half the fluids in his body got ejected in hers. Doug’s wail of pleasure nearly matched Sheri’s, and then I dumped my load inside Sheri to make her the happiest woman in the living room next to Fran.

While they were fucking up a storm, Sheri and I weren’t just watching. We’d moved around as we made love trying different positions. We’d taken over a love seat, and Sheri had been riding me as I decided to end round one so we could join Doug and Fran in a half-time event of refreshment. I blasted a load and filled up my sister-in-law’s pussy. I loved relative relations.

We were still coupled together and cooling down when a loud voice from the foyer said, “Mom, I always knew you had a thing for my uncle. Nice show. You’re a hot fuck. I didn’t know you could cum so hard. By the way, ‘Hi, Steeeeeve.’”

She turned towards her father and Fran and said, “And dad, I didn’t know you had that kind of stamina and energy inside you. My staid opinion of you has just undergone a major renovation. You, too, are a hot fuck.”

I turned partway to greet my niece, remaining coupled to her mother,. “Hi, Lori. Nice to see you.” I ignored my nudity, the fact I was visibly embedded in her Sheri’s pussy, and the further fact that my fiancée straddled her father with his cock still visibly up her cunt.”

Lori said, “You must be Fran. I’m Lori.”

Fran blushed a little, but stuck her hand out past my brother, and said, “Hi, nice to meet you. I don’t think we were expecting you home tonight.” She giggled and even gestured at where she was coupled to Doug. They shook hands but were laughing. Doug was blushing.

Lori laughed, “I guessed that. I decided to come home early instead of staying over. Mark, my boyfriend, has to get up early tomorrow morning for a trip to another college campus for some event.” She turned to her mother, “So, the two of us fucked a couple of times and I decided to come home.”

Sheri whispered to me, “If you pull out of me, I’m going to flood the entire city with your cum. Stay inside me.” I was sure that Lori heard her.

Lori asked, “Was this round one or round two, or don’t you do second rounds at your age?” I wasn’t sure who she was addressing the question to.

Fran spoke, “That was round one, and we were planning on a couple more before the end of the night.” She taunted her future niece-in-law, “Want to join us for the next one?”

Lori lit up like a kid at Christmas, “Could I? You wouldn’t mind? REALLY?” She looked at her mother, obviously a softer touch than her father.

Doug started to sputter from beneath Fran, but before he could speak, Sheri said, “Doug, don’t say a word, and yes, Lori, you may join us if it’s all right with your uncle and his fiancée.”

Fran and I both nodded and muttered words of approval. Lori was a study in teenage beauty with long brown hair that glistened, it was so well cared for, dark set eyes that could stare right into your heart, lips that looks succulent, and a body every supermodel would die for. More than that, she was sex on a stick. I’m sure every male that saw her wanted a piece of her. I was feeling lucky.

Lori came over to me and kissed me really hard on the lips. She whispered, “I’ve wanted to do that for about the past seven years Uncle Steeeeeve. More recently, I’ve wanted to more than just kiss. Tonight, we are going to have some real fun.”

She quickly turned and moved to Fran, and delivered an equally passionate kiss. “So, very nice to meet you in a more friendly way ... my future aunt. I think we’re going to have a really great relationship, too.”
